Like many (at least based upon the countless reports I found in several forums), I experienced problems in transferring the data from the watch through IR to my computer (I've spend hours on it to the point I was ready to return the watch). To make a long story short and not to end up in endless technical reasons why the connection can/cannot work, for everyone having IR connection problems make sure you place the watch next (and I really mean next, just a couple mm, not inches or cm's) to your IR port on your computer. Also, the IR transmitter on your watch is NOT the red bottum but are the 2 very small holes above the letters O and A of POLAR.
Once you do this, it will very likely solve your problem. I had problems connecting with both my laptops, one with a build in IR port, the other with an external (USB) IR transmitter. The watch seems to have a very short IR transmitting range.

Other than that, the watch does what it is supposed to do. I still find it pretty expensive for what it is but there are not a lot of options if you want to have a HR monitor with all these features. I use the watch for swimming, bicycling and running. So far, so good. I have used it for about 50 hours now.

Good luck

I'll start by saying this is a great gadget all-around. It's not something you can just strap on and run out the door with though, you need to read the manual carefully and completely to truly appreciate what this computer can do for you. Also, read all of the HELP file in the Pro Trainer sfotware that comes in the box.

There are so many things this computer can do for your training from beginner to advance that I couldn't possibly comment on them all, so I'll just go over my personal favorites. But first, and extremely brief introduction of myself so you may know if you are receiving usable information for yourself. I am 35 years old, about 50 lbs overweight, having gradually gaining weight over the last 10 years or so from a very healthy frame. I'm no stranger to exercise, except maybe the last several years. I have a gym membership I never use(d) and a perfect 10 mile running trail right outside my office door I never use(d). I am fairly tech-savvy and I lie to play with electronics, but I have no degree in the stuff. I have been trying to get on a running/jogging routine for almost a year now with no success at persistence. Until now...

This watch changed everything. The first thing it when I got it was hook myself up to it and head out the door, turn it on, then stood at the end of my driveway for 30 minutes trying to figure out how to use it. I went back inside with a heart beat of about 150 BPM nopt from exercise, but from frustration. What did I just get myself into? I just want to exercise I don't want a mess of electronics to fight... back inside to read the manual.

I spent an hour reading up on the basics, enough to go back out and get a workout in.

I have no problems with the IR transfer others have mentioned, although this has been problematic on my two previous models (one i broke and one I gave to a friend as an excuse to buy this cool new one). My S610 worked well for the first couple of years but then struggled to connect via IR. One thing I will say is steer very clear of that Polar after marker IR device (see my other review on that specifically). It is an absolute overpriced piece of garbage (I usually don't speak out that strongly against something but after spending $120 on two of them I want to help others not flush good money down the drain). For $20 you can get a Startech model that works flawlessly. I use this monitor 5 days a week and the Polar Precision Performance software that comes with it is solid. I do recommend upgrading to a model that includes this software as their weblink tool is pretty worthless (my wife uses it because her F55 is not supported by the Polar Precision Performance software). Overall though the Polar watches and chest bands are the best.

The RS400 is my fourth Polar monitor. The electronic part, software and ease of use are very well designed and implemented. I must however admit, that I was very disappointed with the poor craftsmanship and materials.

The S610i which served me for many years was battle proven. It was very durable, the glass was not scratched easily, water did not penetrate into the watch easily, and I thought it was the perfect training companion.

This is exactly why I was so disappointed with the RS400. I bought it because of the new look, the fact that polar was shifting most of their production to a new line similar to the RS. Series, the fact that the transmitting belt operated in two frequencies, which enable me to read my pulse while traveling in various gyms of various hotels, and still get WIND technology sleek, no interference operation.

The supporting software is also very good.

Very quickly I learned that the watch is not built very well: the red start button sometimes is quite stubborn, you really have to convince it to operate. The glass is built in such a way that it's being constantly and easily scratched, even on normal, day to day circumstances. The watch is very sensitive to water, and even in very shallow water in the pool you will notice small signs of evaporation on top of the glass.

I tried to ask the Israeli agent how much will it cost to replace the glass and the answer was over US$100.

Unfortunately Polar has stopped producing the former models, and they are hard to get by.

Hope Polar will read some of the customers comments and go back to produce their previous, durable models.
